Active Directory (AD) is a crucial component in managing a network of computers, ensuring security, organization, and efficiency. The installation process of AD and joining a computer to a domain involves several steps, as outlined in the "AD Installation and Joining a Computer to a Domain.pdf". Firstly, to install AD, insert the system disk and run dcpromo in the "Run" dialog box. Follow the installation wizard to proceed with the installation. As the first domain controller in the network, select the option for a new domain controller. Additional domain controllers in an existing domain are used as backup, while creating a child domain within an existing domain or a new domain within a forest requires different selections. Next, input the domain name for the new domain being created. During the process, it is essential to also install DNS as it is necessary for domain name resolution and to locate domain controllers within the network. Choose the operating system compatibility and set a recovery password for Active Directory, which will be required for backup and restore operations in the future. Once the installation is complete, restart the computer. To join a client machine to the domain, navigate to My Computer -> Properties -> Computer Name -> Change -> Domain, and input the domain name to be joined. Verify the identity by entering the domain administrator's username and password for authentication. Overall, the installation of AD and adding computers to a domain is a critical process that ensures the smooth operation and management of a network. By following the specific steps outlined in the "AD Installation and Joining a Computer to a Domain.pdf" document, administrators can effectively establish a secure and efficient network environment for their organization.
